7. Data-driven methods for real-time voltage stability assessment
Abstract : Voltage instability is a phenomenon that limits the operation and the transmission capacity of a power system. An operation state close to the security limits enables a cost-effective utilization of the system but it could also make the system more vulnerable to disturbances. READ MORE

9. On voltage fluctuations in low voltage grids – characterization, propagation and impact on LED lamps
Abstract : The work presented focuses on voltage fluctuations produced by household devices and their impact on the light output of LED lamps. Voltage fluctuations can produce unsteadiness on the light intensity of the lamps, so-called light flicker. An observer may or may not experience light flicker, depending on e.g. READ MORE

10. Voltage Source Converters with Energy Storage Capability
Abstract : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. READ MORE
